Latest signal I've received is strongly skeved. https://drive.google.com/open?id=17sKg-cjm4AEXrY0dK-RujUNF5nuGsGgH Uh, is soo fast. 40m/s it's more than 140km/h _________________ Karol SQ5KVS

EDIT: OK, I can hear it - 440Hz shift, pairs of frames every few minutes (2-3 I believe). QRG was not stable, but now seems to be more fixed. Signal a little to weak for me yet. _________________ -- Pozdrawiam! Krzysiek

Grupa: Użytkownik Posty: 54 #5499627 Od: 2016-5-1	Supercapacitors weigh way to much , even the smaller ones is 0,5-1 gram. I have connected the v-backup direct to solar so it will have a voltage never going under 1,5V which if iirc the lowest voltage needed to keep the the almanac in memory. 73 Mikael

Ciekawe czy na pokładzie jest coś więcej niż APRS _________________ ------------ Pozdrowienia Przemek SP5CMW
